HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 180, 386, 478, 521 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 180, 386, 478, 521 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 180, 386, 478, 521 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 180, 386, 478, 521 is 1.
HCF(180, 386, 478, 521) = 1
HCF of 180, 386, 478, 521 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 180, 386, 478, 521 is 1.
Highest Common Factor of 180,386,478,521 is 1
Step 1: Since 386 > 180, we apply the division lemma to 386 and 180, to get
386 = 180 x 2 + 26
Step 2: Since the reminder 180 ≠ 0, we apply division lemma to 26 and 180, to get
180 = 26 x 6 + 24
Step 3: We consider the new divisor 26 and the new remainder 24, and apply the division lemma to get
26 = 24 x 1 + 2
We consider the new divisor 24 and the new remainder 2, and apply the division lemma to get
24 = 2 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 180 and 386 is 2
Notice that 2 = HCF(24,2) = HCF(26,24) = HCF(180,26) = HCF(386,180) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 478 > 2, we apply the division lemma to 478 and 2, to get
478 = 2 x 239 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 478 is 2
Notice that 2 = HCF(478,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 521 > 2, we apply the division lemma to 521 and 2, to get
521 = 2 x 260 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 521 is 1
Notice that 1 = HCF(2,1) = HCF(521,2) .
